Porous ceramics,Ceramic chuck,Porous ceramic chuck table,Porous Ceramic Partial Vacuum Chuck
Porous Ceramic chuck table
Adhesive surface with planarity of 5μm max.
Brief inroduction
Work pieces can be adhesively fixed by aligning the porous to the body of the metal(or ceramic),and applying negative pressure from the back and sides of the body.
Due to the pores that are very tiny and averagely spread,vaccum chuck would not cause harms and scratch on your work pieces,improving the yield rate,making the best partner of manufacture.
